To all whom t may concern: i

Be it known that I, CARL Binnen, a citizen of the United States, residing at Summit,` in the county of Union and State ofy New'y Jersey, have invented new and useful Improvements in a Stop Device for Sinks, of

which the following is a specification.

The ordinary kitchen sink as commonly used simply acts as a spill for conveniently the device so that itmay be readily attached to the standard sink by merelyv inserting the device in the pipeA fittings forming the discharge. u

The invention is illustrated in the accompanying drawings as follows Fig. Y1 shows a central section of a -sink with the device in place.

Fig. 3 a detached view of the operating cam.

1 marks the sink, 2 the front fold of the ordinary sink, and 3 a rearwardly extending flange forming a space 4 between the reary wall of the sink and the house wall 5 against which the sink may be arranged, 6 a discharge opening in the sink, 7 a nipple extending through the opening` 8 a flange extending from the nipple to form a closure with the sink bottom, 9 a strainer on the nipple 7, and 10 screw threads arranged on the lower end of the nipple. c

A valve body 11 has a screw-threaded end 12 adapted to screw on to the nipple 7 and secure the same inthe bottom o-f the sink in the manner that is ordinarily accomplished by the discharge fitting. The valve body is provided with a diaphragm 13 having the passage 14 through it surrounded by a valve seat. The valve element, or head 15 operates on this seat to close the opening. This body may be of resilient material if desired. A stem 16 extends from the head 15 through a guide 17. The guide 17 is carried by a detachable fitting 18. having the screw threads 19 for screwing into the lower' end ofthe valve body. The fitn isiaaat ting has av downwardly screw-threaded ex-- tcnsion20. The guide -17 is carried by a spider 'A spring 22` is arranged between the valve head and the spider 2l and is of sufficient strength to close the valve when the valve is released. The extension 20 is connected with a pipe 23. by means of the flanged nut 24 and the pipe23 with a trap 26 by means of aslip .joint 25. The trap connects'with thedrain pipe 27 which ordiuarily extends'into the wall..V v

A cam 28 is mountedfona stem 29. The

stem extends throughva stuflingibox guidel 30 and vis provided withv a ,handle `31 by means of which the stem may be'turned, thus actuating th@ carri28 to bringit against and into engagement with the valve so as to open the valve. `The cam is preferably pointed and extends infboth directions so that the handle maybe'turned in either directionto permit the closing ofthe valve. The pointed end of theystem extends into a depression 32 in the top .ofthe valveso as to lock the valve in open-position. The valve stem is provided with a groove 33. Apin 34 extends through the follower of the stuffing box into the screwspthus locking the stem in place. i

`The body is providedwith the passages y35 and 36, the passage 35 communicating with the body above the diaphragm -13 and the passage 36 communicating with the body below the diaphragm'13.' The passage 35 is closed to the body of the valve by a wall 38 and the passage 36 to the body of the valve by a wall 37. The valve body is provided with a flange 39 to which is secured a flange 40 by means of screws 41. The fiange40 has openings registering with the passages 35 and 36 and a pipe 42 extends from theopen-` ing registering with the pipe 3 5 toward the rear and this pipe has an upward extension 43 leading to a return bend 44. `A pipe 45 is connected to the return bend paralleling the pipe 42 and extends to the flange 40 communicating with the opening 36. These passages 35 and 36 with the pipe with its loop forms a bypass around and closing the element of the valveand the upwardly extending loop forms an overflow` for the sink when the valve is closed, the top of the loop determining the level in which liquid may accumulate in they sink. This device may be readily attached to the ordinary discharge sinlrfroin a mere spill to a receptacle which may itself be used for the purpose ot Vwashing dishes or similar uses. rlie valve stein and overflow loops are carried by the body and the valve stein extends to the front of the sink where it inay be readily operated but is so covered by the sink as to cause no inconvenience to the operator and the loop extends into the space which is ordinarily formed by the sink along the rear wall.

Vhat claim as new is:-

lB In la stop device `for sinks, the combina tion of a 'valve body adapted to forni a part or" a 'discharge conduit and having a valve diaphragm with a valve seat tl'ierein; a valve element operating on the seat; a stein on the element; a bypass around the closure 'formed by the element mounted on the valve body and having an upwardly extending` loop extending to the rear; a ifitting detachably secured to the body and having a guide for the stein; a spring tending tov close the valve; -and ineans mounted on the body opposite the loop and extending 'forward to position adapting it to be operated troni the front of the sinkor lactuating the valve element.

2. 1n a stopy device for sinks, the combination of a valve body adapted to forni a part of a discharge conduit and having a valve diaphragm with a valve-seat therein; a valve element operating von the seat; a stem on the element; a itting detachably secured to the element operating element; a fitting body and having a guide 'for the stern; a spring tending to close the valve; and means extending forward from the valve body for actuating the valve eleinen't coni prising a cani, and a stein extending from the cani.

3. ln a stop device for sinks, the combination of' a valve body adapted to form a part of a discharge conduit and having a valve diaphragm with a valve seat therein; a valve on the seat; a stein on the detachably secured to the body and having a guide Jor the stern; a spring tending to close the valveg and in'eans extending forward from the valve body for actuating the valve Aelement comprising a cani adapted to lock the valve in open position and a stein extending from the cam.

e. ln a 'stop deviee for sinlrss the combination of `a valve body adapted to orvin a part of a 'dischar *e conduit 'and having a valve `diaphragm with a valve seat therein; a valve element operating on the seat; a stern on the element; a fitting detachably secured to the body and having a guide for 'the stein; a spring tending to close the valve; neans extending forward from the body for actuating the valve element; and a bypass Aarorlnd the diaphragm mounted on the valve body and having an upwardly extending loop.

ln testimony whereof l have hereunto set my hand.
